Our immune system is the first line in defense against diseases. It is important to provide our bodies with essential nutrients for optimal immune function. Zinc is one of the key nutrients.

What is Zinc?
Zinc is only a trace element, meaning that humans need very little of it each day. A balanced diet is enough to provide the daily recommended serving of Zinc for most people. Zinc is essential for a variety of bodily functions including wound healing, thyroid function, insulin production, storage and immune system.

Zinc can also improve common colds, diarrhea and age-related cataracts when taken regularly as a dietary supplement.
